My LS Swap 6.0/4l80e Twin turbo

Wow, impressed with the hard work and making it happen. I'm dropping mine off, I'm burnt out on messing with these things so huge respect for doing it so clean.

I'm going this route myself but LS2/L92 aluminum combo with CX Racing headers/DP kit, but what turbos you running and what boost or power you looking for?

You use the Holley Dominator computer, not sure which route is practical with stock harness.

In the "FWIW" dept: I took the fuse panel out, removed all the unused wiring, and left the body, lighting and basic power to dash, etc, in place. I used those sources for the Dominator, and other 12V switched devices.
 
Those are Vector 15x8.5 and 275/60 15 DR. Wish the BS was around 4 inches instead of 3.5

Those are 62/62 turbos and as much boost as I safely can! Maybe 22-25 lbs? Factory PCM and a harness that I made.

Same here for the truck harness.
 
Here we go!

Few more minor changes! lol Replaced the intake as I am not putting on a cowl hood. Every time I got into it, I could see that the intake was pushing the underside of the hood! So I went with a Sniper Intake. The runners are almost as long as the High ram so I will see what power is lost or gained next time I head to the dyno. 210 lbs. injectors are now installed as well as a complete e85 compliant fuel system. Will be doing a bracket for the catch can, moving it from its temporary location.
